July 15, 1930. A, JUUL BUILDING CONSTRUCTION Filed Feb. 18, 1927 WI 'TNE S SE5 ATTORNEY Patented duly 15. 1930 were EDWARD ARTHUR JUUL, OF SHEBOYGAN, WISCONSIN BUILDING COIFISTRUCTION Application filed February 18, 1927. Serial No. 169,326.

The invention relates to building construction and to forms for makingconcrete walls and floors.

An object of the invention is to provide a type of building construction by which fireproof structures can be erected ata relatively low cost and in an expeditious manner.

Another object of the invention is to provide simple but eifective metal forms and supporting means therefor by which concrete building walls and floors can be conveniently and readily constructed.

The invention further consists. in the several features hereinafter set forth and more particularly defined by the annexed claims.

In the accompanying drawings. Fig. 1 is a fragmentary transverse sectional elevation of a building skeleton with the assembled wall-defining forms of this invention ready to receive plastic concrete;

Fig.2 is a fragmentary outside elevation of the assembled wall forms and their retaining members;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1, after the wall is poured;

Fig. 4 is a detail perspective view of a form embodying the invention;

Fig. 5 is a fragmentary Eransverse sectional view through a floor of a building with the forms still in place; and

Fig. 6 is a fragmentary transverse sectional elevation of a completed building wall and its footing.

In these drawings. the numeral 10 designates spaced building wall columns. such as H-beams, to which are secured structural floor beams 11 in any suitable manner, as by connection angles 12, either riveted or welded in place. At their lower ends the wall columns 10 are secured to base plates 13 in any suitable manner. as by connection angles 14. the plates 13 being mounted on a concrete footing 15 by anchor bolts 16. The columns 10 are spaced at suitable intervals, as indiright angles to the plane of the building wall and their flanges forming abutments adapted to receive the end portions of metal forms 17. Each form 17, shown in detail in Fig. 4, comprises a one-piece channel of heavy sheet cated in Figs. 2 and 3, with their webs at metal in which the outer flatface of the web 18 is a walldefining surface and the relatively narrow parallel flanges 19 are reenforcing portions. The flanges 19 are provided with inturned marginal lips 20 parallel to the web 18 for further reenforcement and to present support-engaging abutments.

Vhen theforms 17 are employed for the construction of a building wall, they are placed horizontally on edge one resting 6 above the other with the end portions of their flat webs 19 in abutment with the flanges of the wall columns 10, to thereby define a wall cavity bounded by the forms and the spaced wall columns. In order to retain the forms in such position in condition to resist the pressure of plastic concrete in the wall cavity, vertical structural members 21. such as T bars, are disposed in spaced parallel relation adjacent the inner and outer flanges of each wall column 10 to form parallelsided slots on opposite sides of the columns between which the forms 17 may be stacked and retained against lateral displacement. In the present instance. the lower ends of the T bars 21 are removably bolted to connection angles 22 secured to the base plate 16.- The upper end of each inner T bar 21 is removably bolted to a connection angle 23 secured to the underface of the floor beam 11. while each outer T bar 21 has its upper end removably bolted to a bracket 24 detachably secured to the outer face of the adjacent column. The removable form-supporting bars 21 may, of course. be secured in place by other means than that illustrated. Suitable provisions are also made for the inclusion of doors and windows.

lVhen stacking the forms along the columns. wall ties 25 of thin sheet metal may be inserted between the flanges of adjacent forms. and suitable reenforcing bars or mesh 25 may. if desired. be placed in the wall cavity. Plastic concrete is now poured between the stacked forms to build up a wall section 26 together with the adjacent flanged columns which form integral parts of the wall and which lock the marginal portions of the wall slab in place. Since the concrete does not flow through the web portions of the columns. each wall panel may be cast independently of the adjacent wall panels. The type of concrete used is that known as cinder concrete, which is preferred because of its lightness, heat-insulating qualities, and other desirable characteristics. After the sections of concrete wall become set. the forms are removed and used in building other wall sections. The forms can be easily removed by withdrawing them endwise through the guide slots. The forms part freely from the surface of the cast panel .without scoring or defacing the surface and without any need for chipping out bolts, wires, or other projections. At parts of the building frame where the columns are closer together than usual, it is not necessary to provide shortened forms, since the regular longer forms can project through the guide slots and extend beyond the end of the panel.

The same forms 17 may be employed as floor forms, as indicated in Fig. 5, wherein temporary supports 27, such as wooden bars, extend transversely between the floor beams 11 and rest on the lower flanges of the beams, the top surfaces of the supports being spaced sufficiently below the top flanges of the floor beams so that the forms 17 may rest on the supports in laterally contiguous inverted horizontal position and have the upper faces of their webs 18 approximately flush with the top flanges of the floor beams in position to have a superposed floor slab 28 built thereon. In constructing such 'floor slab, the usual wire or barreenforcement may be includedf After the floor slab has set, the forms may be removed downwardly after knocking out the supports 27, this being accomplished by defleeting the supports to askew position. After the lower wall sections are completed, the basement or lowermost floor slab28' may be built in place adjacent the footing 15.

In many cases, the outside of the concrete walls may be covered with a waterproof coating to exclude moisture. The exterior surface of the wall may be finished in various ways, as by stucco, or by brick veneer 29, as illustrated in Fig. 6, wherein the wall ties 9,5 are desirable for reenforcement.

In the construction of the building, the steel skeleton is first completed in accordance with suitable specifications, after which the walls and floor are ready to be made. The setting of the wall forms and -the pouring of the concrete can be done by inexperienced labor under suitable direction, so that labor eosts'can be made relatively low for the work of erection. The type of building construction is such that the concrete walls 26 may be somewhat thinner than is customary in concrete buildings.

.domestic and industrial purposes can be erected in an expeditious manner and at relatively low cost. 4

What I claim as new and desire to secure by Letters Patent is: I

A form structure for concrete buildings, comprising spaced permanent wall columns, upright supports removably disposed on opposite sides of each column and in spaced relation to said column to present form-receiving slots. and removable forms extending between said columns and confined in said slots on opposite sides of said columns to define with said columns a wall cavity adapted to receive plastic concrete whereby said wall cavity is kept free from form-bracing means.

2. A form structure for concrete buildings, comprising spaced permanent wall columns, flanged structural members removably disposed on opposite sides of each column and in spaced parallel relation to each column to present form-receiving slots, and removable forms extending between said columns and confined in the slots on opposite sides of said columns to define with said columns a wall cavity adapted to receive plastic concrete, whereby said wall cavity is kept free from form-bracing means.

' 3. A form structure for concrete buildings, comprising spaced permanent wall columns, removable'forms extending between said wall columns and disposed one above the other in abutment with said wall columns to define with said columns a wall cavity for receiving plastic concrete, and removable upright supports engaging the outer sides of said forms for retaining said forms in engagement with said permanent wall columns, whereby said wall cavity is kept free from form-bracing means. 7

4. A form structure for buildings, comprising a frame including spaced permanent wall columns arranged in the same vertical plane, upright supports removably disposed on opposite sides of the plane of said columns, and removable forms extending between said columns and abutting at their outer sides against said upright supports to define between said forms a wall cavity adapted to receive plastic concrete, each form being of fixed length and being removable endwise from the cast wall panel in a direction parallel to said panel.

5. A formv structure for buildings, com prlsing a frame including spaced permanent wall columns arranged in the same plane and defining the end walls of a wall cavity extending therebetween, upright supports removably disposed on opposite sides of the plane of said wall cavity and in spaced relation to said wall cavity, and removable forms extending between said columns at the opposite sides of said wall cavity to define the side walls of said cavity, said forms abutting at their outer sides against said upright sup ports.

6. A form structure for buildings, comprising a frame including spaced permanent 7 wall columns, upright supports removably disposed on opposite sides of each column and in spaced relation to said column to present vertically disposed-slots, and removable forms extending between said columns to form the opposite sides of a wall cavity adapted to receive plastic concrete, and said forms bearing at their outer sides against said upright supports and adapted to be displaced endwisethrough said slots-in adirection transversely of said slots.
